求大神解答

Question

<item
   android:id="@+id/search"
   app:actionViewClass="android.support.v7.widget.SearchView"
   android:icon="@android:drawable/ic_menu_search"
   android:orderInCategory="200"
   app:showAsAction="ifRoom|collapseActionView"
   android:title="search" />

一直报不能识别我的showAsAction和actionViewClass。。。

Error:(13) No resource identifier found for attribute 'showAsAction' in package 'com.niuniu.actionbar'

Error:Execution failed for task ':app:processDebugResources'.
